EGG-BEATER.

Specification of Letters Patent.

Patented June 4, 1918.

Application filed April 13, 1918. Serial No. 228,414.

' ings.

This inventionrelates to an improved egg beater, and has for its primaryobject to provide a device for this purpose which can be easilymanipulated with a minimum of manual labor to thoroughly beat eggs, orother fluid or semi-fluidmaterials.

It is another important object of the vention to provide an egg beaterwhlch 1s strongand durable in its construction, and

' wherein the several operating parts for the beaterelements are housedand protected so that their accidental injury or interference with theirproper operation is obviated.

It is one of the detailobjects of the inv vention to provide an eggbeater embodying a rotatable head and a cylinder or housing fixed tosaid head, beater elements secured to the head and the housing, a memberlongitudinally movablewithin the housing and operatively connected tosaid head, and a spring within the housing resisting the movement ofsaid member in one direction. It is also a further general object of theinvention to improve and simplify the construction of devices of theabovecharacter so that the same may be produced at small manufacturingcost and to render the same efficient and serviceable in practical use.

With the above and other objects in view, the invention consists in theimproved combination, construction and relative arrangement of theseveral parts as will be hereinafter more fully described, subsequentlyclaimed and illustrated in theaccompanying drawing in which similarreference characters designate corresponding parts throughout theseveral-views, and wherein: Figure 1 is a longitudinal sectional view ofan egg beater constructed in accordance with the preferred embodiment ofmy invention;

Fig. 2 is a section taken on the line 2-2 of Fig. l;

Fig. 3 is an enlarged detail section taken I I on the line 3-3 of Fig.1; and s Fig. 4 is a horizontal section taken on the line H of Fig. 1.

Referring in detail to the drawing, .5

designates a head plate which may be of circular or other form in plan,said plate being provided-with a central opening therein having a spiralthread or rib 6. i

To the outer edge of the head plate 5 at diametrically opposite points,the terminals of the metal straps 7 are suitably secured. The endportions of these straps extend in parallel. relationv for a suitabledistance,

while the medial portions thereof are formed into the opposed laterallybowed sections 8. The medial portions of the respective metal strapsconnecting the bowed sections 8 thereof are disposed in intersectingrelation. to each other.

One end of an elongated cylindrical metal housing or cylinder 9 is fixedto the head plate 5, and to the other or closed end of this cylinder,the terminals of the additional metal straps 10 are securely fixed.These latter straps are also provided with the oppositely bowed portions11 disposed inwardlyof and in spaced relation to the bowed portions 8-of the straps 7. The medial portions of the straps 11 are also disposedin intersecting relation to each other and upon the intersectingportions of the straps 7. These intersecting portions of the severalbeater straps may be riveted or otherwise permanently secured together.Preferably, the bowed portions 8 andll of the beater straps, which aredisposed in the same transverse plane, are connected to each other bythe bracing plates or webs shown at 12 and which also serve asadditional agiany suitable form is loosely engaged upon the bolt 17fixed in the other end of the rod 13 and projecting longitudinallytherefrom.

A coil spring .18 .is arranged .Within the cylindrical housing 9 andbears at one. .ofits ends against the closedend .Wall of said housing.To the other end of this spring a metal disk 19 is fixed, and this, diskis formed with a central conical stud engagedin a bearing recessorcavity formed in the opposed "face of the plate 15. 'Thus frictionalcontact betweenxtheiplateszl5 and 19 is prevented.

.In the operation .ofthedevice above described, and assuming that thespring 1 8 is expanded and the rod 13 is in its normal position, thebowed .portionsof the metal & beater straps, are disposed Within.theeggs or other material contained iii-a suitable receptacle, and therod 13 is then forced longitudinally I through the head plate .5 againstthekactioni offthe spring-:18. In this movementofstherrod, therib orthread 16 engaged in the rotation of "the cylinder orhousing.

Of course 9,:the spring 1 8alsorotates therewith as said springkis gradually compressed. A'lhe plater19on'the-endof thespring 18, being spaced from the :plate 15, may alsofreely rotate with respect to the latter plate. When the i handle 16 .isreleased, the-spring '18 expands and reverses the axial movementofthearod Whereby theflrotation or turning movement of .rthe beatermembers and the parts-connected thereto is also-reversed. Thus,thethorough agitation of the eggs or otherfmaterials with relativelylittle. manual exertion, is obtained.

iFrom the :foregoingdescription taken in connection= With the. accompanying drawing, the construction, :manner of operation and severaladvantages of theinvention Will be clearlypand fully understood. Thedevice as a whole, is relatively simple and strong a and'durableziniits.construction. By providing! the housing}? for theoperating :rod and the spring 218, these parts are protected, so thatthe a material being; agitated cannot collect thereon orother foreignmatteivfind its Way betweenthe coils of the springor the plates :15 and,19 and interfere .With the pro-percoperation of the device. I haveillustratediin the accompanying drawing, a certainn-number-Jandarrangement offthe metal beaterstraps,-: bu:t it is manifest that agreater or less number of suchstraps may be employed .and they may 'beotherwise constructed than as herein shown. The device is-alsosusceptible of many other modifications in 'i'the form, proportion andarinvention as claimed.
